What it does

Openai API is an agent skill from ynulihao/AgentSkillOS. Build with OpenAI's stateless APIs - Chat Completions (GPT-5, GPT-4o), Embeddings, Images (DALL-E 3), Audio (Whisper + TTS), and Moderation. Includes Node.js SDK and fetch-based approaches for Cloudflare Workers. Use when: implementing chat completions with GPT-5/GPT-4o, streaming responses with SSE, using function calling/tools, creating structured outputs with JSON schemas, generating embeddings for RAG (text-embedding-3-small/large), generating images with DALL-E 3, editing images with GPT-Image-1…

Its SKILL.md is about 5.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering LLM API integration, Embeddings and Structured output and tool calling. It works with OpenAI, Node.js and Cloudflare Workers. The repository describes itself as: Build your agent from 200,000+ skills via skill RETRIEVAL & ORCHESTRATION.

When your agent uses it

  • : implementing chat completions with GPT-5/GPT-4o
  • Streaming responses with SSE
  • Using function calling/tools
  • Creating structured outputs with JSON schemas

Example prompts

  • “/openai-api”

Requirements

  • Node.js
  • A credential in OPENAI_API_KEY

Workflow steps

12 steps, taken from the first numbered list in SKILL.md.

  1. Quick Start
  2. Chat Completions API
  3. GPT-5 Series Models
  4. Streaming Patterns
  5. Function Calling
  6. Structured Outputs
  7. Vision (GPT-4o)
  8. Embeddings API
  9. Images API
  10. Audio API
  11. Moderation API
  12. Error Handling

What it can do on your machine

Read from SKILL.md and the folder at commit c3cfae1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.openai.com

    Also links to:

    • platform.openai.com
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openai API loads about 5.9k tokens when it runs. Until then it costs about 202 tokens; SKILL.md has 1,163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~202
When it runs · the whole SKILL.md, loaded when a task matches
~5.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:67
    Or create `.env` file:

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,163 words (~5,889 tokens).
